Abstract
The electric lamp has a pinched seal (2) which is fixed in a lamp cap (5) with a metal shell (9) with cylindrically bent portions (10) by means of a retaining member (11). The retaining member (11) has a set of brackets (12, 13) between which the pinched seal (2) is clamped in. The clamping force (P) is generated in that the brackets (12, 13), after being inserted in the lamp cap (5), are moved away from one another through openings (14) in the lamp cap before being fixed to the shell (9) of the lamp cap (5).
